- The eye sees with a part called the retina.
- The retina has many different cells.
- Cells send signals about color and motion.
- Scientists found retinal cells work together.
- Cells share signals through small electrical links.
- This sharing helps when light is weak.
- Researchers studied mouse retinas and human retinas.
- The work comes from Yale researchers.
- The finding may help understand eye disease.
